Thanks for the quick response!

Browsers may not implement it unless it is mandated in the spec. Since
browsers already have HTTP transport, I am afraid the browsers will end up
just supporting HTTP as the only transport for the video tag. Since RTSP is
the major streaming protocol and since HTML5 is supporting multimedia
playback experience within the browser, including RTSP in the spec could
completely do away with the need to have stand-alone RTSP clients installed
or properitery plugins/solutions especially for live streaming. I think it
makes everyone's life a lot easier knowing that there is a standard player
engine present on every PC (through browser) that supports HTTP and RTSP in
multimedia tags instead of worrying about the numerous proproeitery
streaming protocols (based on HTTP) that are coming up with recently.
